Those appearances marked the first instances the two have been seen together in almost a month, following a short split. A source had told E! News they are "still together but taking things a bit lighter." Kylie and Tyga have not commented about their relationship recently.

"I ask Kylie...'I think you were just somewhere for New Year's with him' and then like one day, they're not together," Khloe told E! News' Catt Sadler exclusively. "That's the life of an 18-year-old...So I stopped asking her, because it's confusing and I hate telling people, 'Oh, they broke up' and then all of a sudden, someone pulls in my driveway and I'm like, 'Oh, s--t, I thought we were done with this one.'"

"I'm just as confused!" Khloe said, joking, "I need like a 'Note to self—who is everybody dating in this family.'"

Khloe and Kylie's sister Kendall Jenner, 20, had sparked romance rumors herself recently...rumors involving Harry Styles, 21, with whom she recently vacationed in St. Barts, where Tyga had joined the Kardashian and Jenner family this past summer. The two have not commented on the status of their relationship.

Khloe's interview took place ahead of the Jan. 20 premiere of her new FYI network talk show, Kocktails With Khloe.
